Quality Control

Our Diisopropylnaphthalenesulphonic Acid is produced under stringent quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and physical characterization, to meet exacting customer requirements. A Certificate of Analysis (COA) documenting purity, identity, and key specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. Keep away from strong bases and oxidizing agents.
